First of all

Hiya papaya! have a beautifull day full of blessings and health!!

I found alittle trick in able to get any desire you want, and also, it helps gets collectives too!!!

When you get a Side quest Mission such as "deliver X item" or "kill X enemy" it dosnt matter, you can get a random item each time you reload your game!

Example here, i went with the Side quest Deliver


As you can see, it says, " Talk to vincent" , So lets check in map!


AHA! your there!! lets go visit her!

Once im with her, before talking, we save the game!, After it we can talk to see wich reward ill get, geez, i need 1 mithril for that armor for my tank.


Nu-uh! thats not the item i need! reload again and Re-talk to her again!


Oh woah!, thats a good one but atm i dont need it sowy >.<, RELOAD!


Booya! i got it! , now i can hop happily to the armor to create my armor!

*ehem*

So yea XD , whenver you give away/finish the quest, make sure to save and reload till it appears the item you want!, it also works for the "collections" since they give random ones, like i got lots of books,etc.
